ABSTRACT: Recent studies have shown that AMPKα2 can regulate epithelial-mesenchymal transition(EMT) processes during kidney fibrosis. However, the underlying mechanisms for AMPKα2 changes in renal tubular EMT remain unclear. TGF-β1 was used to induce epithelial-mesenchymal transition(EMT) in normal rat renal tubular epithelial (NRK-52E) cells. Gene microarray was used to analyze differential gene expression in EMT-derived NRK-52E cells before and after the AMPKα2 knockout
Project description:Renal tubular epithelial cells are the main cells affected in the process of renal fibrosis, and it has been shown that mesenchymal stem cell-derived exosomes can treat renal fibrosis, and then the traditional 2D-EVs production method is inefficient. We efficiently extracted 3D-EVs by coaxial bioprinting, but the mechanism of 3D-EVs for treating renal fibrosis is not yet known. Therefore, we used TGF-beta1 to induce a renal fibrosis phenotype in NRK-52E cells and took 2D- and 3D-EVs for treatment in order to explore the possible differential molecular mechanisms of 2D- and 3D-EVs for renal fibrosis. This approach facilitates the discovery of new mechanisms for exosomes to treat renal fibrosis.
Project description:Chlorothalonil (2,4,5,6-tetrachloroisophthalonitrile) is a widely used broad spectrum fungicide. Despite its common use, chlorothalonil is classified by IARC as Group 2B, a possible human carcinogen, with formation of renal tubular adenomas and carcinomas in rats of both sexes and in male mice. In this study we have examined the effect of sub-cytotoxic exposure to chlorothalonil at 6h, 24h and 72h on the whole-genome expression profile in a rat proximal renal tubule cell line (NRK-52E). We used microarrays to detail the mechanism of toxicity and possibly carcinogenicity.
Project description:In this study we have examined the effect of sub-cytotoxic exposure to aristolochic acids (1.65µM) at 6h, 24h and 72h on the whole-genome expression profile in a rat proximal renal tubule cell line (NRK-52E). We used microarrays to detail the mechanism of toxicity and possibly carcinogenicity of aristolochic acids in rat renal proximal cells. NRK-52E cells were cultured to confluence on 6-well plates. Cells were then exposed to aristolochic acid dissolved in DMSO (0.1%) at the IC10 concentration at 72h (1.65 ?M) or DMSO only as control. After 6h, 24h and 72h the medium was removed and RNA was extracted from the cells. Three studies were conducted at each time point.

Project description:We generated the Erbin-deficient NRK-52E sublines (referred as to KO) using CRISPR/Cas9 approach, and performed transcriptome sequencing to identify the differentially expressed genes compared to the control (referred as to NC).
Project description:We used Affymetrix GeneChips to expression profile rat kidney NRK-52E cells treated with control scrambled siRNA or siRNA specifically targeting Adamts16. The goal of this project was to identify the downstream genes regulated by Adamts16 (the function of Adamts16 has yet to be fully delineated). Gene expression differences resulting from these siRNA-mediated gene knockdown experiments will be compared to the gene expression profiling experiments comparing kidneys from Dahl salt-senstive hypertensive inbred strain versus less hypertensive S.LEW(D1MCO4x1x3Bx1) congenic strain. The S.LEW(D1MCO4x1x3Bx1) congenic animal is an S rat containing the LEWIS allele for Adamts16 instead of the S allele. Gene expression differences in the kidneys of S.LEW(D1MCO4x1x3Bx1) versus S are hypothesized to result from sequence differences between the S and LEWIS alleles for Adamts16. It is further hypothesized that allelic differences in Adamts16 in inbred rats is responsible for blood pressure variance. The downstream genes regulated by Adamts16 may provide insight pertaining to the mechanism of blood pressure differences. Experiment Overall Design: RNA from 3 independent cultures of NRK-52E cells treated with scrambled control siRNA was extracted for target preparation and hybridization onto Affymetrix GeneChips. We also isolated RNA from NRK-52E cells treated with two different siRNAs targeting Adamts16 (n=2 independent cultures for each siRNA) for target preparation and hybridization onto Affymetrix GeneChips.
Project description:Monuron (1,1-dimethyl-3-(4-chlorophenyl) urea) is a non-selective phenylurea herbicide, widely used in the developing countries, however concerns have been raised about it toxicity and carcinogenicity. Monuron was evaluated by the National Toxicology Program (1988) and shown to be a male rat-specific renal carcinogen; however the mechanism of carcinogenesis is unknown. In this study we have examined the effect of sub-cytotoxic exposure to monuron (250M-BM-5M) at 6h, 24h and 72h on the whole-genome expression profile in a rat proximal renal tubule cell line (NRK-52E). In addition we examined the short term exposure of MON in kidney and liver of exposed rats. We used microarrays to detail the mechanism of toxicity and possibly carcinogenicity of monuron. NRK-52E cells were cultured to confluence on 6-well plates. Cells were then exposed to chlorothalonil dissolved in DMSO (0.1%) at the IC10 concentration at 72h (1.1 M-NM-<M CHL) or DMSO only as control. After 6h, 24h and 72h the medium was removed and RNA was extracted from the cells. Three studies were conducted at each time point. Eight Wistar-derived rats where bred in the Life Science Support Unit at Liverpool John Moores University male rats (190-240g) 7-9 weeks of age were used in this study. Four rats being dosed with MON at 40mg/kg body weight on day 1 and 400mg/kg body weight on days 2 and 3, at 5ml/kg in corn oil. Four control animals were dosed with corn oil at 5ml/kg. Seventy two hours after the last dose all rats were killed by a rising concentration of carbon dioxide, the liver and kidneys quickly removed and immersed in RNAlater.
